| // Table captions are full block-flows, which is why they inherit from |
| // LayoutBlockFlow. This is the only internal table part that allows margins. |
| // All other elements simply ignore it to satisfy the table model. |
| // |
| // This class is very simple as the logic for handling the caption is done in |
| // LayoutTable. In particular, the placement and sizing is done in |
| // LayoutTable::LayoutCaption. The function is called at different timing |
| // depending on the 'caption-side' property: "top" is laid out before table row |
| // groups when "bottom" ones are laid out after. This ensures that "top" |
| // captions are visually before the row groups and "bottom" ones are after. |
| // |
| // See http://www.w3.org/TR/CSS21/tables.html#caption-position for the |
| // positioning. |
